I need a MORE PRECISE Sliding Stretch

Hey everyone,

I’m trying to correct the tempo of a piano roll which is speeding up over time. Using the sliding stretch feature, I seem to have hit a limit with the precision.

What I’m doing is setting the composition to the maximum sample rate, then using the length of the composition to change the amount of sliding stretch. However, I need MORE precision, as the 7 minute long recording is still slightly faster/slower by the end.

I need it to be about where the black line is, in between the two samples. Anything I can do to achieve this? Willing to use other software.

I’m using a time track for a very precise sliding stretch now.

However, I still need a way to change the speed very precisely. Audacity apparently does calculations up to 10 decimal points, is there any way to make edits that precisely?
